SHIP-RETARDING DEVICE.

Application filed January 22, 1921.

To all 4.071 am it may concern Be it known that I, LOUIS JoNnzio, acitizen of J ugo-Slovakia, residing at Joliet, in the county of Will andState of Illinois, have invented certain new and useful Improvements inShip-Retarding Devices, of

which the following is a specification.

This invention relates to certain new and useful improvements in shipretarding de vices, and has particular reference to the provision ofhinged plates carried by the outer sides of the hull of a ship normallylying in flat engagement therewith and adapted to be projected laterallythereof for retarding the forward travel of the ship.

The primary object of the invention resides in the provision of anattachment to a ships hull adapted to be moved to a position to preventthe forward movement of a ship to retard such movement and bring theship to a sudden stop to prevent collisions and other accidents.

A further object of the invention embodies a device for retarding theforward travel of aship in the form of plates hinged to the outer sidesof the hull of a ship with each plate being independently operable forretarding the forward movements and also capable of cooperation with theships rudder to provide for a short turning of the ship.

With these general objects in view and others that will appear as thenature of th invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated in the accompanying drawings, andpointed out in the appended claim.

In the drawings forming a part of this application, and in which likedesignating characters refer to corresponding parts throughout theseveral views,

Figure 1 is a side elevational view of a ship equipped with the presentinvention showing the movement-retarding plates lying adjacent the sidesof the ships hull,

Fig. 2 is a top plan view of the same showing the plates extendedoutwardly,

Fig. 3 is a detail horizontal sectional view showing the side plateslying adjacent the sides of the ships hull with the mechanism forprojecting the same,

tion of one of the arcuate guides for one of the guide rods of theretarding plate.

Fig. 6 is a detail sectional view showing the operating gears and therack bar for shifting the retarding plate and Fig. 7 is a crosssectional view taken on line VII-VII of Fig. 5.

Referring more in detail to the accompanying drawings there isillustrated a ship 1 of any conventional type equipped with the presentform of device for retarding the forward movement thereof, the devicesembodying plates 2 hinged to opposite sides of the ships hull andnormally assuming a position in engagement with the sides as shown byfull lines in Figs. 1 and 2 with the plates adapted to be projectedlaterally of the ship to the dotted line positions shown in Fig. 2 forretarding the forward movement.

The plates and their specific mountings together with the operatingmechanism therefor are shown more clearly in Figs. 3 to 7, the plate 2being hinged at its forward edge as at 3 to the outer side of the shipshull. To provide a guiding means for the swinging end 2 of the plate,the hull of the ship is provided with spaced vertically alined arcuatetubes 4 extending inwardly of the hull as shown in Fig. 3 with thecurvature of the tubes centering on the plate hinges 3. i

A curved link 5 pivoted as at 6 to the inner face of the plate 2 extendsinto the tube 4 and carries a plunger head 7 at the inner end thereof,the tube being closed at its inner end to prevent the entrance of waterfrom the tube into the interior of the ship.

The mechanism for projecting the plates 2 laterally of the sides of theship embodies an arcuate rod 9 centering on the hinge connection 3 andpivoted at its outer end as at 10 to the inner face of the plate 2, therod 9 passing through a boss 11 and a packing gland 12 of water-tightconstruction.

A bracket 13 carried by the inner face of the ships side has a pinion 11 journaled in the inner end thereof in engagement with rack teeth 15formed in the base of a groove upon the inner side of the rod 9, shownmore clearly in Fig. 6. A gear wheel 16 fixed to a shaft 17 journaled inbrackets 18 is in constant engagement with the pinion 14 and uponrotation of the shaft 17 the gear and pinion are revolved to effectmovement of t e rod 9.

In the operation of the device, a suitable source of power applied tothe shaft 17 rotates the gear 16 and pinion 14: to move the rod 19outwardly of the sides of the shaft as shown in Fig. 2, the plate 2moved outwardly upon its hinge connection 3 being guided and braced bythe arcuate rods 5. The plunger heads 7 upon the inner ends of the rodwill cushion the movements of the plates in opposite directions, theplunger heads being of slightly less diameter than the arcuate tubes lto permit the escape of water at the periphery thereof. Should a ship,equipped with this device encounter an obstruction, the plates 2 may bemoved outwardly to retard the forward movement thereof, and either ofsaid plates may also be alone operated to provide a short turning of theship. 7

While the form of the invention herein shown and described is what isbelieved to be the preferred embodiment thereof, it is nevertheless tobe understood that various forms, modifications and arrangements of theparts may be made without departing from the spirit and scope of theinvention as claimed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is A ship retarding device in combination witha ship, hinged plates carried by'the sides thereof, arcuat'e tubularmembers carried by said ship. guide rods carried by said plate extendinginto the'ship and having a longitudinal groove cut in the face at theinner are thereof with rack teeth formed in the bottom of the groove, apinion journaled adjacent the arcuate rod and having one edge extendinginto the rod groove for engagement with the rack teeth, and a verticalshaft carried by said ship having a gear upon one end for engagementwith the said pinion and the pulley upon the opposite end for rotatingsaid shaft. I

In testimony whereof I affix my signature.

LOUIS J ONEZIC.
